go around your house and hit (or tap) ten different objects. the objects should be different shapes and made of different material (choose things to hit that won’t each object is a different medium for sound. try to hit each using the same amount of energy.

describe each object that you hit. what is its shape and what is it made of? then describe how it sounds to you. does it transmit sound well? does it absorb sound? is the sound loud or soft? is there a “ring” to the sound? does it sound like a “thunk” or does it sound like a drum?

rank the ten objects from loudest to softest.

draw some conclusions based on your results from steps 1 and 2. for example, are there a certain shapes or materials that are better or worse media for sound travel?
